Monitoring device used for producing compositions

ABSTRACT

The present invention is directed to a monitoring device for producing a target composition, such as an automotive paint or an architectural paint. The device includes a client computer in communication with a host computer and means for dispensing required items for making a desired amount of the target composition. The computer readable program code means in the computers identify one or more formulas associated with identification criteria of the target composition and dispense through means for dispensing the required items listed in the formula. The code means search for the required items in the various inventories, including updating the inventories if required. The device can be also used to control the inventory by shipping just in time any components required to produce target compositions, such as refinish tints used in automotive refinish paints.

FIELD OF INVENTION

The present invention is directed to monitoring production of compositions and more particularly directed to monitoring paint cans and paints contained therein during their life cycle.

BACKGROUND OF INVENTION

During the production of compositions, such as automotive paints, several components are mixed in a certain desired proportion to produce a composition. For example paint shop users visually match the required color to a color reference chip from a color reference chip manual supplied by Du Pont Company, Wilmington, Del., which also provides the manufacturer's paint code. Alternatively, the paint shops can use a software tool called Vindicator® locator software supplied by DuPont Company to locate the VIN number/manufacturer's paint code, and then translate it to a DuPont formula code. However, these paint codes still need to be matched to a color formula. Once the formula that matches the paint code is found, components in quantities listed in the formula are manually poured into a receiving container positioned on a stand-alone scale. Typically, no data are kept for future use and no inventory of dispensed components is maintained. Some shops use semi-automated dispensing systems, such as a dispenser connected to the ColorNet® PC dispensing system supplied by YADA Systems, Roseville, Minn. The user manually weighs-out component quantities in accordance with a formula. The quantities of dispensed components are recorded in a database. If the dispensed quantities are above a present acceptable tolerance, the dispensing system can recalculate the component quantities to bring the batch back into an acceptable tolerance level. Printouts of the quantities of the dispensed components can be stored or printed out for future reference. Alternatively, some paint shops use X-Pert™ Paint Mixing System supplied by YADA Systems, Roseville, Minn. connected to ColorNet® PC dispensing system. The X-Pert™ System prompts the user to load a receiver, such as paint can, into a receiving fixture. The controller manipulates the fixture to dispense the correct amount of component. When that component has been dispensed, the next component is loaded in the fixture. The process is then repeated until all the components listed in the formula are dispensed. Resulting data are saved for later use.

A major problem associated with the forgoing systems is that these systems do not control the quality or types of components used in producing a target composition. As there is no monitoring of the dispensed components used to make the target composition, it is possible in the current processes to use inferior quality component or a wrong component. As result, it is not possible in the current processes to produce target compositions of desired predictable quality. The process of the present invention and the device used therein address the foregoing issue as well as provide means for monitoring the life cycle of the components, from the day they are produced by their manufacturer to the day they are dispensed by the user.

An object tracking and management system disclosed in U.S. Pat. No. 6,600,418 B2 utilizes radio frequency identification (RFID) tags to identify and move objects during the manufacturing process. However, need still exists to monitor production of compositions of desired quality.

DETAILED DESCRIPTION OF PREFERRED THE EMBODIMENT

Compositions, such as automotive paints used in OEM (original equipment manufacturer) or refinish application, are typically prepared by mixing required items in quantities listed in one or more formulas. The required items are dispensed from current items in current inventory, such as one or more stock compositions that match a target composition, target components listed in the formulas, or a combination thereof. Sometimes, the current inventory may not have sufficient quantity of stock compositions required for making a desired quantity of the target composition, or a target component listed in the formula may be missing in the current inventory, or a combination thereof. Thus, supplementary items from a supplementary inventory may be required to augment the current inventory such that the required items can be dispensed to make the desired quantity of the target composition.

It should be understood that the term “composition” as used herein refers to compositions that include liquid components; solid components, such as powders, granules, or pellets that can be conveyed through conventional conveying means, such as pneumatic conveyers; or a mixture of liquid and solid components. Typical target compositions that can be produced by a device and the process of the present invention include OEM automotive paints, refinish automotive paints, architectural paints, industrial coating compositions, fragrances, dyes, printing inks, ink jet inks, lubricants, cements, nail polishes, flavors, food colorants, eye shadows, deodorants, shampoos, hair conditioners, adhesives, perfumes, caulks, masonry wall repair kits, catalyst blends, pharmaceutical drugs, food additives, polymer blends, blends of reactants; blends of food products, such as ready-to-use soups, cake mixes, spice mixtures, coffee blends, ice cream blends; or a point-of-purchase consumer products. The present invention provides for a device and a process used therein to monitor production of such compositions and more particularly directed to monitoring paint cans and paints contained therein during their life cycle.

FIG. 1 illustrates the broadest aspects of the preferred embodiment of a-monitoring device 1 of the present invention. Device 1 includes a client computer 10 and a host computer 12 in communication with client computer 10 via a conventional communication link 14, such as modem, internet, local area network, or a wireless communication system. A conventional client computer usable storage medium 16 is located in client computer 10 and a conventional host computer usable storage medium 18 is located in host computer 12. Client computer 10 is preferably provided with a conventional monitor/key board 20 and a conventional printer 22. Client computer 10 and host computer 12 can be any known computer/processor such as those supplied by Dell Computer Corporation, Round Rock, Texas or IBM Corporation, Armonk, N.Y that can be configured to execute conventional computer program codes.

It should be understood that client computer 10 and host computer 12 can be located anywhere, such as for example computer 10 can be located in one country, such as the United States, or another state and host computer 12 can be located in another country, such as Canada, or another state. Alternatively, host computer 12 can be located in one country, such as United States, or another state and client computer 10 can be located in another country, such as Canada, or another state. It should be further understood that host computer 12 could be in communication with plurality of client computers 10.

Device 1 further includes means for dispensing 24, the details of which are provided in FIG. 2. Storing means 34, such as racks, can be employed to store current stock 26, indicated by a dotted line box, which typically contains one or more stock composition containers 26A and one or more stock component containers 26B. Current stock 26 can be augmented with a supplementary stock 28, indicated by dotted line, which typically contains additional quantities of stock compositions stored in additional stock composition containers 28A and any missing stock components contained in missing stock component containers 28B. It is contemplated that stock compositions, additional quantities of the stock compositions, stock components or any missing stock components could also be brought to device 1, as required, from a storage area. It should be understood that the various aforedescribed containers could be arranged in any other manner, if so desired, as the physical positioning of such containers is not critical.

Stock information on containers can be provided through identification tags such as, stock composition information on stock composition identification tags 30A affixed to stock composition containers 26A, stock component information on stock components identification tags 30B affixed to stock component containers 30B, additional stock composition information on additional stock composition identification tags 34A affixed to additional stock composition containers 28A and missing stock component information on missing stock components identification tags 34B affixed to missing stock component containers 28B.

The aforedescribed tags can be bar code tags, conventional RFID tags, or a combination thereof where the bar code can be printed on top of the RFID tags such that the information contained in the tag can be read with either bar code reader or conventional RFID interrogator. RFID tag system is preferred. A basic RFID system typically includes an interrogator that includes an interrogator antenna or coil, and a transceiver (with decoder); and a transponder provided with a transponder antenna or coil (RFID tag), wherein the transponder is electronically programmed with unique information. The interrogator antenna emits radio signals to activate the tag and read and write data to it. Antennas are the conduits between the tag and the transceiver, which controls the system's data acquisition and communication. Antennas, which are available in a variety of shapes and sizes can be built into a frame to receive tag data from articles passing or positioned near the frame. Frequently, the interrogator (a.k.a. reader), which is packaged with the interrogator antenna and the transceiver/decoder to can be configured either as a handheld or a fixed-mount device. The interrogator emits radio waves in ranges of anywhere from few millimeters to 30 meters or more, depending upon its power output and the radio frequency used. When an RFID tag passes through or near the electromagnetic zone, it detects the interrogator's activation signal. The interrogator decodes the data encoded in the tag's integrated circuit (silicon chip) and the data is passed to the host computer for processing.

RFID tags come in a wide variety of shapes and sizes and are categorized as either active or passive. Active RFID tags are powered by an internal battery and are typically read/write, i.e., tag data can be rewritten and/or modified. An active tag's memory size varies according to application requirements; some systems operate with up to 1MB of memory. In a typical read/write RFID work-in-process system, a tag might transmit to a machine a set of instructions, and the machine would then report its performance to the tag. This encoded data would then become part of the tagged part's history. The battery-supplied power of an active tag generally gives it a longer read range. The trade off is greater size, greater cost, and a limited operational life (which may yield a maximum of 10 years, depending upon operating temperatures and battery type). Typical RFID tags and method of producing them is disclosed in the U.S. Pat. No. RE37,956E, which is incorporated herein by reference.

By contrast, passive RFID tags operate without a separate external power source and obtain operating power generated from the interrogator. Passive tags are consequently much lighter than active tags, less expensive, and offer a virtually unlimited operational lifetime. The trade off is that they have shorter read ranges than active tags and require a higher-powered interrogator.

RFID systems suitable for use in the present intention preferably operate at frequencies ranging from 125 KHz to 2.45 GHz. The significant advantage of all types of RFID systems is the non-contact, non-line-of-sight nature of the technology. Tags can be read through a variety of substances such as dirt, crusted grime, and other visually and environmentally challenging conditions, where barcodes or other optically read technologies would be useless. RFID tags can also be read in challenging circumstances at remarkable speeds, in most cases responding in less than 100 milliseconds. The read/write capability of an active RFID system is also a significant advantage in interactive applications of the process of the present invention.

One or more conventional interrogators 32A and 32B can be used to read the stock composition information, stock component information, additional stock composition information and missing stock component information. Some of the typical bar code readers include Maxiscan 2210 supplied by Intermec Technologies Corporation of Everett, Wash. or MC9000-G supplied by Symbol Technologies of Holtsville, N.Y. and some of the typical RFID interrogators include Model 915 or 2450 supplied by Alien Technology Corporation of Morgan Hill, Calif.; Fasttrack LRP or HMS models supplied by Escort Memory Systems of Scotts Valley, Calif.; and Models MP9111, MP9112, MP9210, MP9320, and 13.56 all supplied by Samsys Technologies, Inc. of Richmond Hill, Ontario, Canada. Some of the typical combination bar code reader/RFID interrogators include Model 1555 supplied by Intermec Technologies Corporation of Everett, Wash.; or Model HHR supplied by Matrics, Inc. of Columbia, Md. When the aforedescribed containers are made of metal or metal alloy, such as steel, RFID tags are preferably disposed on an insulated substrate, such as paper, plastic film, or a resinous coating, such as a painted surface, to insulate RFID tags from the metal containers. It is contemplated that RFID tags, including tag antennas could be directly printed on the aforedescribed containers by using conductive ink or conductive ink jet ink printing process developed, for example, by Carclo PLC of Wakefield, United Kingdom.

The stock composition information on stock composition identification tags 30A affixed to stock composition containers 26A, stock component information on stock components identification tags 30B affixed to stock component containers 26B, additional stock composition information on additional stock composition identification tags 34A affixed to additional stock composition containers 28A and missing stock component information on missing stock components identification tags 34B affixed to missing stock component containers 28B. One or more conventional interrogators 32A and 32B can be used to read the stock composition information, stock component information, additional stock composition information and missing stock component information.

The stock composition information on stock composition identification tags 30A can include identity of the stock composition, compositional structure of the stock composition, quantity of the stock composition contained in the stock composition container, price of the stock composition contained in the stock composition container, serial number of the stock composition container, place of manufacture of the stock composition, location of the stock composition container, date of manufacture of the stock composition, date of expiration of the stock composition, toxicity information of the stock composition, MSDS of the stock composition, manufacturer of the stock composition and contact information thereof; or a combination thereof.

The stock component information on stock component identification tags 30B can include identity of the stock component, compositional structure of the stock component, quantity of the stock component contained in the stock component container, price of the stock component contained in the stock component container, place of manufacture of the stock component, location of the stock component container, date of manufacture of the stock component, serial number of the stock component container, date of expiration of the stock component, toxicity information of the stock component, MSDS of the stock component, manufacturer of the stock component and contact information thereof; or a combination thereof.

The additional stock composition information on additional stock composition identification tags 34A can include identity of the additional stock composition, compositional structure of the additional stock composition, quantity of the additional stock composition contained in the additional stock composition container, price of the additional stock composition contained in the additional stock composition container, place of manufacture of the additional stock composition, location of the additional stock composition container, date of manufacture of the additional stock composition, serial number of the additional stock composition container, date of expiration of the additional stock composition, toxicity information of the additional stock composition, MSDS of the additional stock composition, manufacturer of the additional stock composition and contact information thereof; or a combination thereof. It is contemplated that the additional stock compositions can be the same as the stock compositions or they can be one or more additional stock compositions that match on the basis of preset criteria.

The missing stock component information on missing stock component identification tags 34B can include identity of the missing stock component, compositional structure of the missing stock component, quantity of the missing stock component contained in the missing stock component container, price of the missing stock component contained in the missing stock component container, place of manufacture of the missing stock component, location of the missing stock component container, serial number of the missing stock component container, date of manufacture of the missing stock component, date of expiration of the missing stock component, toxicity information of the missing stock component, MSDS of the missing stock component, manufacturer of the missing stock component and contact information thereof; or a combination thereof. The present invention contemplates adding one or more missing stock components to any stock compositions that do not match the formulas associated with the identified characteristics so that such modified stock compositions could then be utilized as target compositions.

In one of the embodiments, means for dispensing 24 further include conventional means for conveying, such as tubes or pipes, to convey the contents from containers 26A, 26B, 28A and 28B via respective conventional dispenser nozzles 26AA, 26BB, 28AA and 28BB to an identified target composition receiver 38, which is provided with a target composition identification tag 39, which can be read by or written to by an identification interrogator 41, which is similar to the ones described earlier. Alternatively, it is contemplated that a single dispensing nozzle, instead of the aforementioned plurality of nozzles, could be employed to convey the contents from the various aforedescribed containers to receiver 38. One type of dispenser apparatus suitable for use in the present invention is described in PCT application having International Publication Number WO 03/084653A1.

Dispenser nozzles 26AA, 26BB, 28AA and 28BB are in communication with client computer 10′, such that the opening and closing of dispenser nozzles 26M, 26BB, 28M and 28BB can be controlled by client computer 10′, in accordance with the formula. It should be noted that quantity of contents dispensed from current stock 26 and/or supplementary stock 28 can be controlled on a volumetric or preferably on a gravimetric basis. To control the dispensed content on the volumetric basis, dispenser nozzles 26AA, 26BB, 28M and 28BB could be provided with conventional means to determine the volume of dispensed items. Alternatively, or in conjunction therewith, dispensing means 24 can be provided with means 40 for weighing the required items dispensed into identified target composition receiver 38. Means 40 typically include a conventional weighing scale 40, such as Model KB60sx supplied by Mettler-Toledo Incorporated of Columbus, Ohio or Model SC2CCE-SX supplied by Sartorius AG of Göettingen, Germany, on which receiver 38 can be positioned. Typically, means 40 include means 42 for generating a signal upon completion of dispensing of the required items in accordance with the required inventory and then transmitting the signal to client computer 10′ via means 43 for transmitting the signal to client. Means 43 can be configured to transmit the signal to host computer 12 (shown in FIG. 1), or to client computer 10′ and host computer 12. Alternatively or in combination thereof, it is contemplated that one could manually read off the amounts of dispensed items displayed on a weighing scale and then manually enter the data into client computer 10′.

It is further contemplated that once the dispensing process is completed, one can, using identification interrogator 41, write and/or print to target composition identification tag 39 a target composition information that includes the identity of the target composition, compositional structure of the target composition, quantity of the target composition contained in target composition content receiver 38, price of the target composition contained in the target composition content receiver 38, place of manufacture of the target composition, location of target composition content receiver 38, date of manufacture of the target composition, serial number of target composition content receiver 38, date of expiration of the target composition, toxicity information of the target composition, MSDS of the target composition, manufacturer of the target composition and contact information thereof; or a combination thereof. Interrogator 41 can be a barcode label printer/RFID writer, such as Easycoder F2 or F4 supplied by Intermec Technologies Corporation if Everett, Wash. or Model R-140 or R-402 supplied by Zebra Technologies International of Vernon Hills, Ill.

In order to allow the user to make the target composition closer to the place of customer's business, it is contemplated that device 1 could be built as a transportable device in which the relevant portions of device 1 are installed in a van or a trailer that could be driven to the customer's place of business where the target composition can then be made.

In device 1 client computer usable storage medium 16, host computer usable storage medium 18, or both have computer readable program code means 15 loaded therein for monitoring production of a target composition, which can be written by using conventional programming software, such as C++ Builder, Version 5 or Delphi, Version 6, both supplied by Borland Corporation located in Scotts Valley, Calif. Details of computer readable program code 15, shown in FIGS. 3A and 3B, include:

Means 50 for configuring computer readable program code devices to cause client computer 10 or host computer 12 to identify one or more formulas associated with the identification criteria of the target composition, the formula providing a required inventory for making the desired amount of the target composition. For example, the identification criteria of the target composition in the form of an automotive paint can include, one or more of a manufacturer name, make, model, year of production, color name, paint code, cross reference information, intended use, VIN number, or spectrophotometric data of a vehicle or its color. The identification criteria can be entered manually by the user in client computer 10 or it can reside on an identification criteria identification tag, such as RFID tag or bar code tag positioned on a vehicle or on a color reference chip supplied by a manufacturer, in which case the user can then use a conventional identification interrogator to read off and enter the identification criteria directly from the tag into client computer 10. It is understood that for some other uses, such as architectural coating compositions, other types of identification criteria, such as a manufacturer name, year of production, color name, paint code, cross reference information, intended use, or spectrophotometric data of a wall or its color, could be employed. The characteristics associated with the identification criteria typically include, for example, color characteristics, such as conventional L,a,b color data or spectral data; the volatile organic content (VOC); pH of aqueous compositions; appearance characteristics, such as flop of metallic paint compositions; coefficient of friction; and viscosity. The required inventory, which is based on the formula includes information on required items such as (a) one or more compositions matching the characteristics and quantities thereof required to make the desired amount of the target composition; (b) target components and quantities thereof listed in the formula that are required to make the desired amount of the target composition; or a (c) combination of (a) and (b).

Means 52 for configuring computer readable program code devices to cause client computer 10 or host computer 12 to generate a current inventory, which includes information on the current items, such as (a) one or more stock compositions matching the characteristics and quantities thereof required to make the desired amount of said target composition; (b) stock target components and quantities thereof listed in said formula that are required to make the desired amount of said target composition; or (c) a combination of (a) and (b). The current inventory typically refers to the items that can be readily dispensed by device 1 before the dispensing of the required items listed in the required inventory, and would include current stock 26 and supplementary stock 28. The current inventory is then entered into client computer 10 before the required items are dispensed by means 24 for dispensing. If there were no changes, such as replenishing of any depleted stock compositions or stock components or removal of such items from storing means 34, it may not be necessary to renter the current inventory since it was not changed during the previous dispensing cycle. As shown in FIG. 4, means 52 also include means 53 configured to cause client computer 10 or host computer 12 to receive (a) the stock composition information on stock composition identification tags 30A read by one or more identification tag interrogators 32A, (b) the stock component information on stock components identification tags 30B read by identification tag interrogators 32A, (c) the additional stock composition information on additional stock composition identification tags 34A read by identification tag interrogators 32B, and (d) the missing stock component information on missing stock components identification tags 34B read by said identification tag interrogators 32B.

Means 54 for configuring computer readable program code devices to cause client computer 10 or host computer 12 to terminate production of the target composition if the current inventory does not match with a stored inventory, such as, for example, if the amounts of various items in the current inventory exceed those amounts stored in the stored inventory. The stored inventory typically results from updating of the current inventory during the previous dispensing cycle. The stored inventory can be stored in storage medium 16 on client computer 10, or preferably on storage medium 18 on host computer 12. If desired, the stored inventory can be simultaneously stored in storage media 16 and 18. Means 54 allow the user to employ stock compositions, or stock components or missing stock components that meet the quality requirement of these items listed in the formula, i.e., only the genuine pre-approved items can be used. Means 54 also prevent the user from refilling or reusing the previously used up containers (dead containers), such as a stock composition container or stock component container whose contents had been used up earlier. As a result, the manufacturer or the supplier of the stock composition, or stock components has up-to-date real time inventory of these items and can then readily re-supply these items based on the up-to-date real time information available from the stored inventory, which the manufacturer or the supplier can obtain by accessing the stored inventory residing on client computer 10 or host computer 12.

Means 56 for configuring computer readable program code devices to cause client computer 10 or host computer 12 to continue production of the target composition if the current inventory matches with the stored inventory.

Means 58 for configuring computer readable program code devices to cause client computer 10 or host computer 12 to compare the current inventory against the required inventory to ascertain whether the current inventory fulfills said required inventory. Thus, if one or more component listed in the formula is missing or if less than the desired amount of the stock compositions is available in the current inventory it would be clear that the current inventory fails to fulfill the required inventory.

Means 60 for configuring computer readable program code devices to cause client computer 10 or host computer 12 to generate a supplementary inventory if the current inventory partially fulfills the required inventory. It would be clear to one of ordinary skill in the art that means 60 would not be utilized if in means 58 it was determined that the current inventory does fulfill the required inventory. The supplementary inventory includes information on (a) additional quantities of the stock compositions required to produce the desired amount of the target composition, (b) any missing stock components that match the target components listed in said formula in sufficient quantities required to produce the desired amount of the target composition, or (c) a combination of (a) and (b).

Means 62 for configuring computer readable program code devices to cause client computer 10 or host computer 12 to dispense through means 24 for dispensing the required items listed in the required inventory from current items listed in the current inventory, supplementary items listed in the supplementary inventory, or a combination thereof to make the desired amount of the target composition.

Means 64 for configuring computer readable program code devices to cause client computer 10 or host computer 12 to generate an updated inventory. As shown in FIG. 5, means 64 comprise means 65 for configuring computer readable program code devices to cause client computer 10 or host computer 12 to (a) deduct from the current inventory dispensed quantities of the stock composition, the stock components, or a combination thereof to generate an adjusted current inventory; (b) deduct from the supplementary inventory dispensed additional quantities of the stock composition, dispensed quantities of the missing stock components, or a combination thereof, to generate an adjusted supplementary inventory; and (c) add the adjusted current inventory and the adjusted supplementary inventory. The aforementioned sum then becomes the updated inventory. It should be noted the updated inventory would then become the stored inventory in the subsequent dispensing cycle.

Computer readable program code 15, shown in FIG. 6, further includes:

means 66 for configuring computer readable program code devices to cause client computer 10 or host computer 12 to search a first database for identifying one or more characteristics associated with the identification criteria of the target composition; and

means 68 for configuring computer readable program code devices to cause client computer 10 or host computer 12 to search a second database for identifying one or more said formulas associated with the characteristics.

The first database can be stored on client computer 10 and the second database can be stored on host computer 12. Alternatively, the first and the second database can both be stored on host computer 12 in communication with client computer 10, or the first and the second database both can be stored on the client computer 10.

The process and the device of the present invention helps in eliminating the dispensing of poor quality substitution of components listed in the formula, thereby preventing the production of sub-standard compositions. The integrity of the quality of the composition can be maintained by identifying each stock composition or stock component container with a unique identification number, which can be stored by a component manufacturer as soon as the contents in those containers are produced (becomes part of the stored inventory). As a result, the manufacturer can generate and maintain complete information, including the quantity contained in the containers. As the contents in the container are consumed, an updated inventory can be transmitted to the manufacturer by allowing the manufacturer access to client computer 10 or host computer 12, which can be alternatively operated by the manufacturer. The updated inventory then becomes the current inventory in the subsequent dispensing cycle provided the user, such as a collision repair shop, makes no unauthorized additions or deletions to the current inventory. Once the contents in a certain identified container are consumed or depleted, the code associated with that container is relegated to a dead-container list. If the user, by commission or omission attempts to use the same container by filling it with any other unrecognized component, the current inventory would fail to match with the stored inventory, thereby terminating the process. Thus, the process of the present invention helps in ensuring the product quality of the composition.

Additionally, since the manufacturer is aware of which component has been used up, the manufacturer can automatically augment the user with those depleted components without any formal request from the user, thereby reducing the time require to supply the components consumed by the user. Moreover, the manufacturer can also assist the user in reducing his inventory by supplying the components, just in time as they are used up. Moreover, the manufacturer can also bill the user on an “as-used-basis” for the cost of only the stock composition or components actually consumed. As a result, the user's out-of-pocket cost can be reduced. Finally, by using a transportable embodiment of the device of the present invention, the manufacturer could produce the composition at the user's place of business, thus further reducing the user's need to maintain an extensive and expensive inventory.
